The 71-year-old Michigan woman arrested last month after police found her naked and having sex with a younger male companion in the back seat of her Buick was fined $585 and sentenced to a probationary term after she pleaded no contest today to a misdemeanor charge.

Rita Daniels entered her plea to a disorderly intoxication count this morning in District Court in Farmington Hills. Prosecutors dismissed an indecent exposure charge that had been filed against the septuagenarian following her September 3 arrest with Tim Adams.

Adams, 54, today also entered a no contest plea to disorderly intoxication (and had an indecent exposure charge dropped by prosecutors). He was placed on a year’s probation (like Daniels), fined $785, and ordered to perform 50 hours of community service.

As detailed in a City of Farmington Police report, Daniels and Adams (who was also nude) were discovered trysting inside the vehicle (license plate: DIVA 145), which was parked in front of a pair of restaurants. The car was rocking gently and its windows had steamed over, noted Officer Andrew Morche.

After opening the Buick’s passenger door to break up the Saturday evening clinch, Morche asked the naked pair what they were doing. Adams provided a succinct reply: “I’m fucking this chick."

Cops subsequently learned that Daniels and Adams, pictured in the above mug shots, had met for drinks at a nearby bar “before moving to the back seat of the Buick.”
